All wiring Shall have not less than 600 volt insulation and all power wiring and bus shall be in compl.-te conformity with the National Electric Code and M State and local and NF.MA Electrical Standards. Control wiring shall be color i coded. All field connections and connections required to conveniently replace control components shall be made at approved type terminal blocks with en- graved bakelite marker strips. Complete wiring diagrams shall be prepared specifically for this project and submitted for approval along with technical data on components. 35,1no.9.i. Equipment_ The control shall have the following equipment, fea- tares and construction: I. Fused main disconnect with fuses sized as shown on the plan. Disconnect shall he suitable as a service entrance disconnect switch. 2. Auxiliary power manual transfer switch, rotary tvpe or equal. 3. Provide on the side of the control panel an Appleton #AE-1041 RS, 4 wire, 4 pole, 100 amp, 230 volt auxiliary power receptable. 4. Terminal blocks for power, pumpa, floats and future telephone line connections. 5. A lightning arrestor shall be supplied in the control and connected to each line of the incoming side of the power input terminals. The nrrc,,tor shall protect the control against damage due to lightning strikes on the incoming power line. Arrestor shall be of the solid-state type, designed to clamp within 20 microseconds under high level transient surge. Thyrite or carbon type arrestors are not acceptable. contractor shall connect a suitable earth ground to ground lug in enclosure, as required by the National Electric Code. 6. The control center shall include a three phase monitor/control connected to the incoming side of the power input terminals. The unit shall provide instantaneous drop -out protection in the event of phase, unbalance, phase loss, phase reversal, incorrect phase .egnence or low line voltage (under 1.� voltage). The phase monitor shall include automatic reset circuitry and a time delay to prevent drop -out ,iiie to momentary transients. 7. A thermal magnetic molded case circuit breaker ("F" frame or better) shall be supplied as branch circuit protection for each pump motor. 8. A full voltage across the line magnetic mot, or starter with ambient -compensated, quick -trip overload sensing in each phase to provide over current and running protection for eakh pump lnot•)r. -)ver current protection shall be provided by accurately sized replaceable hest-r elements. Units requiring replacement of completo overload block to match motor current are not acceptable overload reset +hall extend through inner panel door. Auxiliary contacts shall he provided for the control functions specified. 1i,100- 0-584Ic Copyright 1Q83 Ronestroo, Rosene, An.ierlik 4 Associates, Inc.
